i have new drop in bar-sto barrel for my hk uspc .i have tried 180 grain rainer with power pistol,unique,and bluedot.i get nothing under 4 inches at 25 yards.it has less than 100 rounds down range.will it get better ? i can put the 357 sig barrel in, it's a factory barrel and it will shoot just over 2 inches at 25 with just about any load.i could not load my 357 sig's to shoot as bad as the 40 does even if i tried.i have 4 357 sig's.could it be a bad barrel ? how many rounds do i try before i call it a bad barrel.will a jhp or a fmj bullet help.or is it that a bar-sto will not shoot a rainer bullet,thanks,keith
